Abstract :
A class-E resonant DC/DC power converter is introduced and verified experimentally. It is composed of a class-E zero-voltage-switching inverter and a class-E zero-current-switching rectifier. Therefore, it offers high efficiency at high frequencies. The measured DC/DC efficiency was 82.64% at full load with 7.3-W output power. A relative frequency range of only 6.12% was sufficient to regulate the DC output voltage at 20 V for load resistances ranging from 55 Omega to infinity.
